At the end of IPL live-cast at IGN, the game director came on to announce it as a world exclusive news tidbit.

I already have the game on my PS3 so not sure that I would necessarily get the PS-Vita version... except that it might be a little less embarrassing to play with the hard to earn costumes on a handheld.

They should keep porting PS3 fighters onto the vita.. since it could run them almost on par with ps3.. and it can offer cross play against ps3 players.. cross play and near ps3 quality gameplay would be a huge selling point for PSv
